Film simulations from scratch using Python
Disclaimer: The post is more about understanding LUTs and HaldCLUTs and writing methods from scratch to apply these LUTs to an image rather than coming up with CLUTs themselves from scratch. Outlin…

Far Cry: How the Fire Burns and Spreads (2012)
INTRO A few years ago, I got the opportunity to architect and code the fire propagation system in Far Cry 2. At that time, it was a gigantic task and it scared the hell out of me. Luckily, it turned out well enough. With the upcoming Far Cry 3, several people recently asked me how

Replacing my Octopress blog with 200 lines of Babashka
Seven years ago I started writing about my adventures with Clojure. I started using Octopress back then and was still using it until today. Octopress worked great for my blogging purposes and I'm grateful that it existed. However, in recent years I became frustrated with the experience of using it, which is probably…

Understanding x86_64 Paging
I’ve spent quite a lot of time messing with x86_64 page tables, understanding address translation is not easy and when I started learning about it I felt like a lot of the material out there on how it works was hard for me to wrap my head around. So in this blog post I am going to attempt to provide a kind of “what I…

Extracting Super Mario Bros levels with Python
For an upcoming project, I need to extract level data from the classic 1985 video game Super Mario Bros (SMB) . More precisely, I want to extract the background imagery for each stage of the game, excluding HUD elements and moving sprites, etc.

In-Depth Ruby Concurrency: Navigating the Ruby Concurrency Landscape
I was honored to present a talk on Ruby concurrency at RubyConf 2024. It represents a high-level distillation of much of my writing and research over the past year. The conference itself was great, and presenting was such a fun experience. Here is the talk, titled “In-Depth Ruby Concurrency: Navigating the Ruby…

Micro C, Part 3: Generating LLVM
In part 2, we completed the user facing part of the compiler with semantic analysis. Now we're free to focus on the backend, generating LLVM. To do so, we'll use the llvm-hs-pure library, which embeds LLVM into a Haskell ADT, allowing us to manipulate it without having to set up any FFI.|A blog about various…

Love C, hate C: Web framework memory problems
I love C. I could give you rational reasons for that. Like the fact that it works everywhere and how it goes fast. But mostly I love C because when I write C I feel an intimate connection with my computer. To me, C has soul. In fact all my personal project are written in C, like the graphics rendering engines that I'm…

So you want to write Java in Neovim
I have been doing Java in Neovim for quite a while at work, and it’s been a very pleasant experience. As Neovim usage grows (especially amongst the younger crowd), I want to share how I do it.

Configuration files are user interfaces
We have all been there. Your software keeps growing and you feel the need to make it customizable. It is too soon for a full-blown UI with all the bells and whistles, so your pragmatic instinct suggests a text-based configuration file. Yes, that’s exactly it! You rejoice knowing the software’s configuration will be…

A first look at WebAssembly performance
WebAssembly gives us the promise to run high performance code in the browser in a standardized way. Now that there are a few WebAssembly previews available I decided it’s time to take a look at their performance. One source for benchmarks is the well known Computer Language Benchmarks Game and I decided to pick nbody…
